power: reset: msm: Clarify restart and poweroff
When PSHOLD in a Qualcomm platform is deasserted the PMIC will perform
either a power off or a restart of the system. The action to take is
configured in the PON block, which is controlled by a separate driver.
As the configuration logic was added to the pm8941-pwrkey driver the
comment in do_msm_poweroff() is no longer valid and the name
do_msm_restart() is misleading. Update the naming and drop the comment.
